No. But historical results are not a guarantee for the future.
It is very easy to make a heapdump with jmap and analyze it with MAT
(http://www.eclipse.org/mat/) or other tools as suggested by others on this
list.

Thanks Chuck.
Is there any danger in taking a heap dump on our system running in production?
Will it cause a significant performance hit or other nasty?
Thanks again,
Greg

Use a heap profiler to find out what's eating up the space and who is
allocating it. Even the simple one (hprof) included in the 1.5 JDK will tell
you that. Better ones (e.g., jhat) are available in 1.6, if you're willing to
move up. There are also numerous 3rd-party profilers available, with YourKit
being a favorite of many.
